Hi everyone! I'm very new using Amplify Shaders and I'm struggling with something I think it's very basic. I tried to look in the documentation and for tutorials but I still haven't figured it out. I want to create a circle mask that works in screen space, the circle is in the middle of the screen and only shows the content in that area. My issue is by creating the mask and placing it in the middle of the screen... do you know any tutorial or resources I can look at to achieve this effect? Thanks so much!
